See above running when I open Explorer OR Firefox......I am assuming these are really slowing PC down.Any answers as to what they are &how I can remove greatfully received..Have recently run FULL scans using MSSE,Malwarebytes,AdAware all now show clear.

Re: Do I have a virus ?

Download CCleaner and run it to clear your temp files etc. Also run the registry scanner on it. When it offers a back up of registry,accept it. If you have BTYahoo toolbar installed uninstall it and likewise for any other toolbars installed. In CCleaner you can check what is running at startup. Have a look there and take a note of what is starting. If you see anything that appears suspicious and you're not sure report back here and you'll be given info what to do.

Re: Do I have a virus ?

Thanks gg30340....have done as you suggested...I said originally all scans reported clear, however downloaded new definitions from MSSE today...rescanned and it has found another 3 infected files with the Trojan :JS/Medfos A and X.

Just finished another full scan and all appears ok now ...fingers crossed......MS explanation of this trojan makes sense...latest update for Medfos released today.

It might be worth doing a scan in safe mode just to make sure you have got everything removed. It is also worth getting CCleaner and running that and checking what is starting at start up. It can give you a heads up to whats using resources.

Re: Do I have a virus ?

Thanks for that pp. It gets the green light on Site Advisor. I looked through the page on the link and it appeared to be how I would expect to remove the virus manually. It may be that the OP's antivirus has done a good enough job and he won't need to manually intervene.

Re: Do I have a virus ?

Thanks guys for info so far...am having one or two problems getting into safe mode at the mo, so have done a couple more AV scans -all appears clear and Task Manager shows no unknown apps running after start up.....so, may just keep a close eye open for a while. (plus do not profess to be totally PC literate)

But have one further question you may be able to answer....msconfig-Startup shows this item ticked for startup :-
